Luckily it was not my reaction, but this is the reason why fluorinated componds are pretty expensive. This black thing in the flask and the condenser is the reaction product, a gunk from a Swart’s reaction, what is a halogen exchange reaction done with Swart’s reagent (antimony trifluoride).
Usually Swart’s reagent changes every single chlorine atoms on an organic molecule to a fluorine, but the high reaction temperature often cause the decomposition of the reaction mixture and forms a black tar, just as in this case.

“In 1986, Gloria Steinem wrote that if men got periods, they ‘would brag about how long and how much’: that boys would talk about their menstruation as the beginning of their manhood, that there would be ‘gifts, religious ceremonies’ and sanitary supplies would be ‘federally funded and free’. I could live without the menstrual bragging – though mine is particularly impressive – and ceremonial parties, but seriously: Why aren’t tampons free?”

jessicavalenti: We need to move beyond the stigma of “that time of the month” – women’s feminine hygiene products should be free for all, all the time.

October 26: Favourite quote or one-liner?

Anne Travers response to “what’s a girl like you doing in a job like this?” is gold. The sad thing is, this was filmed back in the 60’s and we’ve barely moved forward since then.

I used to think the worst thing in life was to end up all alone. It’s not. The worst thing in life is to end up with people who make you feel all alone.

- Robin Williams (1951 - 2014)
